How are Solid Rivets Different from Tubular Rivets?

Solid rivets and tubular rivets are two different types of fasteners with distinct characteristics and applications. Here are some differences between solid rivets and tubular rivets.

(1)Structure:

Solid rivets are made from a solid piece of metal. They consist of a cylindrical shaft with a head on one end and a tail on the other. The tail is typically longer than the shaft and is used to form the rivet by deformation during the installation process.

Tubular Rivets: Tubular rivets, on the other hand, have a hollow structure. They feature a cylindrical body with a hollow center and a head on one end. The hollow center distinguishes tubular rivets from solid rivets and provides flexibility and specific advantages.

(2)Installation:

Installing solid rivets involves driving the rivet through pre-drilled holes in the materials to be joined. The tail end is then deformed by methods such as hammering, rivet squeezers, or hydraulic presses. The deformation causes the tail to expand and fill the hole, creating a secure joint.

Tubular rivets are also installed by passing them through pre-drilled holes. However, their installation process differs from solid rivets. After inserting the tubular rivet, the hollow end is expanded by either mechanical means or heat. Mechanical expansion tools, such as rivet guns or rivet squeezers, deform the hollow end to create a tight connection.

(3)Strength and Load Distribution:

Solid rivets provide excellent strength and load-bearing capacity due to their solid structure. When installed properly, they create a permanent joint that is resistant to vibration, pulling or shearing forces. The solid shaft distributes the load evenly across the joint, enhancing its overall strength.

While tubular rivets may not offer the same strength as solid rivets, they still provide reliable connections for various applications. The hollow structure of tubular rivets allows for some flexibility, which can be advantageous in certain scenarios. The load distribution in tubular rivets is slightly different, with the expanded hollow end acting as a mechanical lock, securing the rivet in place.

(4)Removability:

Solid rivets are considered permanent fasteners since their installation involves deforming the tail, making removal difficult. To disassemble a joint secured by solid rivets, the rivet needs to be cut or drilled out, potentially damaging the surrounding materials.

Tubular rivets, although generally intended for permanent joints, offer more potential for disassembly compared to solid rivets. If removal is necessary, the expanded hollow end can be deformed back to its original shape, allowing the rivet to be extracted without damaging the materials. However, this process requires specific tools and may not always be feasible.

(5)Applications:

Solid rivets are widely used in various industries and applications that require permanent and strong connections. They are commonly found in structural steelwork, bridges, aircraft manufacturing, automotive assembly, and heavy machinery.

Tubular rivets are often employed in applications that require a lighter connection or where some flexibility is desirable. They are commonly used in leatherwork, luggage, belts, and other applications that involve joining thin or pliable materials.

According to these differences, the required rivets can be selected according to the needs, there are many manufacturers specializing in the production of rivets, which can provide a wide choice in terms of type, material, size, and surface treatment.
